Water Resource Management

Groundwater

Groundwater hydrology is an interpretive science: we can't observe the aquifers directly so we must interpolate and extrapolate our understanding from water-level measurements from observation wells. Stevens has expertise for measuring both water quantity and water quality.

Soil Monitoring

Over the past few decades, soil monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related to soil hydrological processes. Monitoring soil moisture conditions provides important information for the protection of, and in the understanding of local and regional water resources.

MEASUREMENTS TO MIND

Getting environmental data to the point of actionable information has historically compartmentalized the data flow path into separate components—sensors, data logger, telemetry, power management, software.

MEASUREMENTS TO MIND (M2M) is a growing suite of Stevens products that embraces cloud-computing with an all-inclusive vision of shortening the communication path from the sensors to data on-line. That is, what the sensors MEASURE the MIND sees. Cloud computing and the rapidly expanding “Internet of Things” is merging this communication path into a complete, integrated system that is all configured, controlled, and interacted with on-line, from one central point.

M2M is:

Meticulous dedication to RELIABILITY through power conservation.

Commitment to unrivalled SIMPLICITY.

Advanced engineering that dramatically LOWERS THE COST of installing and maintaining an environmental monitoring station.

Collected data is sent automatically to either Stevens-Connect or forwarded to any other destination you specify. Because it’s a 2-way cellular connection, you can send configuration changes back down to eTracker or interact directly with connected SDI-12 sensors.

eTracker: Cellular Gateway to the Cloud

Most of our pre-packaged systems are built around eTracker. The reasons? Setup is simple, all configuration and programming is done on the web, you don’t need a data logger, and it works with any analog or SDI-12 sensors. Your data is backed up locally and automatically sent to the cloud-based destination of your choice.

Stevens-Connect

Stevens-Connect is a cloud-based data acquisition and management software system that enables the collection, analysis, reporting, and storage of data from remote monitoring locations. As cloud-based software-as-a-service (SaaS), Stevens-Connect streamlines the data management process and can be accessed from any computer or smartphone with Internet connectivity.

Cell-Net

Cell-Net is a simple cellular telemetry solution for new or existing remote monitoring stations. Unlike typical cellular modems which have a constant high power draw, Cell-Net operates almost entirely in an ultra-low power mode yet still provides the benefits of 2-way communications, and optimizes successful transport of data for maximum reliability.

Web-Based Station Management, Data Access and Data Processing

Access all current and historical data from any Internet-connected device, anytime.

Benefits of M2M

Unprecedented dependability

Ultra-low power consumption: eTracker and Cell-Net run in a 1.6mA power mode when not transmitting or receiving data, yet are still able to respond to incoming calls. This ensures your battery can last through extended periods of non charging.

Remote restart: SOLO allows you to power-cycle your entire station, remotely and on-demand, or on a schedule. This provides the most common remedy for station failures without a costly site visit.

Data redundancy: Prior data set can be transmitted with current data set to avoid missing critical data transmissions caused by busy cellular communication networks.

Data connection verification: Before transmission, connection to the cellular network and the HTTP/FTP server is verified. Data is saved to the buffer for the next scheduled transmission if after several attempts the connection cannot be verified.

Predict and prevent problems: Station and transmission health and performance data (RSSI, battery voltage, load current, solar voltage, internal temperature, MEID or IMEI number, and more) can be logged and included in every transmission.

Instant problem alerts: Set up notifications for problems that occur or will likely occur without having to monitor status, and ensure data will always flow.

Extreme power efficiency means reduced power system requirements, yet still providing 2-way communications, low cellular data cost and the high data throughput you can’t get with GOES or other satellite telemetry.

Eliminate the cost, hassle and additional power draw of a data logger: Cell-Net connects directly to a smart (logging) sensor, eTracker connects directly to any analog or SDI-12 sensors. It’s “plug-and-play”—no special cables required.

All configuration and programming can be done at any time from any device.

Eliminate trips to the site to reconfigure data logger, diagnose problems or power-cycle the station.

Lower your station purchase and maintenance costs

The easiest way to connect your sensors to the cloud

Both Cell-Net and eTracker handle the connection of any serial data received through the RS-232 port to an IP destination.

Web-based device management application requires no training or special knowledge to setup or configure.

All M2M systems have a simple 3-step setup process:

Connect sensors.

Connect power source.

Configure data handling (frequency, redundancy, destination) with the simple online interface. This last step is performed after leaving the site.

Everything required to forward your data to an Internet destination is included:

No need for special cables.

No other hardware required.

No need to purchase, install, configure or update proprietary software.

No need to hire programmers or consultants.

Multiple ways to trigger a transmission: Transmit data based on schedule, or triggered by external logger/sensor, after scheduled collection, or after data buffer reaches set size.

Reconfigure at will: Configuration can be changed at any time from any computer or smartphone with an Internet connection.

Any destination for your data: Retrieve data any way you want, from 3rd-party software to raw data in a universally accessible location and format. Data can be sent to any HTTP/HTTPS or FTP destination via HTTP, FTP, IP or any combination of these protocols.

Any carrier: Can be ordered pre-provisioned or use your own choice of cellular service. Any carrier (GSM or CDMA).

Stevens M2M remote communications products (Cell-Net and eTracker) offer lots of flexibility for getting your data from a remote site. And don’t forget that reconfiguring how and when data is sent can be done anytime, from any device using the web-based interface. Multiple ways to trigger a transmission: transmit data based on schedule, or triggered…
